Key Concepts in Science
-
Theory vs. Law
- Theory: Well-substantiated explanation based on evidence (e.g., theory of evolution).
- Law: Statement that describes an observable phenomenon (e.g., Newton's law of motion).
-
Variables
- Independent Variable: Manipulated in an experiment.
- Dependent Variable: Measured in response to changes in the independent variable.
-
Peer Review
- Evaluation of scientific work by experts in the field to ensure validity and reliability.
Importance of Science
- Drives technological advancement.
- Informs policy decisions.
- Enhances understanding of the universe and our place within it.
- Contributes to solving global challenges (e.g., climate change, health crises).
Ethical Considerations

-
Question
- Formulating specific questions to explore based on initial observations.
-
Hypothesis
- A proposed explanation for the observed phenomenon, serving as a starting point for investigation.
-
Experimentation
- Conducting controlled experiments to test the validity of the hypothesis.
-
Analysis
- Involves interpreting collected data and evaluating results to draw conclusions.
-
Conclusion
- Determines whether the initial hypothesis is supported or refuted by experimental evidence.
-
Communication
- Sharing of research findings with the scientific community to foster further inquiry and validation.
Key Concepts in Science
-
Theory vs. Law
- Theory: A well-substantiated explanation based on substantial evidence, such as the theory of evolution.
- Law: A statement that describes a consistently observable phenomenon, like Newton's laws of motion.
-
Variables
- Independent Variable: The factor that is manipulated during an experiment.
- Dependent Variable: The factor that is measured in response to changes in the independent variable.
-
Peer Review
- A critical process where scientific work is evaluated by field experts to ensure the research's validity and reliability.
Importance of Science
- Science drives technological advancements, influencing daily life and industry.
- It informs important policy decisions by providing evidence-based insights.
